Tert-butyl methyl ether on heating with anhydrous HI in ether gives

Options

A. `CH_(3)OH+(CH_(3))_(3)Cl`
B. `CH_(3)I+(CH_(3))_(3)COH`
C. `CH_(3)I+(CH_(3))_(3)Cl`
D. None of the above

Answer

B

Explanation

If favours `S_(N)2` reaction and the nucleophile `I^(-)` attacks the less hindered methyl group.
`I^(-)+CH_(3)-overset(o+)underset(H)underset(|)O-overset(CH_(3))overset("| ")underset(CH_(3))underset("| ")"C "-CH_(3)overset(S_(N)2)rarrCH_(3)I+CH_(3)-overset(CH_(3))overset("| ")underset(CH_(3))underset("| ")"C "-OH`
